11.118 ZI XIIIRII of the terminal sections 7 and 8 is similarly lfinished, while the mating extremities of v recess 18 of the section 5,

'these two terminal sections are'slant-faced in the manner indicated by the numeral 9.

This mating of the terminal segments peri' mits the removal inwardly of the section 7 from the ring form, as shown by the dotted lines v10 of Fig. 1, without disturbing the position of the segment 8 in its full line form in this figure. The segment 8 may also be removed from its full line position, as will be later explained, to thedotte'd line Each of the Aradially matin of all-of the sections is provide with a face plate 12 adapted to take up the wear accruing upon the section portions during frequent assemblages and disassemblages .'of-l the segments. Each segment is provided with a rounded edge 13 which 'conforms to the inner tire diameter, and whichk narrows down along theslant lines 14 to an integral web member 15. The successive web members 15 of the separate sections are provided with vgrooves 16 which are adapted to mate to form a continuous annular groove when the sections are in their assembled relation. One, or more, of the adjacent extremities of the webs 15 of each pair of mated coresegmeiits is beveled off in the manner denoted by the numeral 17. One of each pair of these adjacent web extremities is provided with an angular recess 18, while the mating web extremity 19 of the adjacent core segment isformed with an integral tQ-ngue 20 which is adapted to project within the lrecess during a mating of the adjacent core segments. The tongue 20 is formed with a hinge recess 21 of semi-cylindrical section, this hinge recess being adapted to encounter the similarly shaped hinge pin 22 which is fixed-across the mouth ot the recess 18 in the adjacent core segment. y

The foregoing description oi the hinge connevtions between adjacent segments does not apply to the slant ends of the terminal core sections 7 and 8, since no hinge connection i provided between these membei-sof the co e. The slant mating line 9 of these terminal segments. is continued, at an angle,

through the webs 15 of thescgments along" the slant line 23. These terminal segments are, however, each hingedly connected upon the separate` extremities of the base sections 5 and 6, the latter being also hingedly connected at their adjacent extremities.

When it is desired to assemble the core of this invention, the tongue 20 of the base section G is approached'and passed into the with the wear plates covering the extremities of these sections angularly separated. In this manner the hinge recess 21 is seated upon the half ginge 22,midthe sections are then permitted position denoted by the numeral-11."\..;\

end faces `to swing about this half hinge connection until the wear plates are in contact. When thus assembled with the tongue 2O in the recess 18, the sections will resist separation ,except by a reverse movement of the sections about ltheir hinge connections until their -remote extremities are approached .A sufiic'iently to permit of the removal of tht tongue 20 from the opposite recess 18.

Each of the terminal core sections l7 and 8 'is preferably provided with the locking tongue 20 or male portion forming part lof each hinge connection, while the recess 18 or fe'male portion of the hinge connection is provided in each of the separated extremities of the base sections 5 and 6.

' In continuance of the giescriation, of the assembling process, assuming t at the base sections have been properly assembled as set forth, the terminal section 8 is similarly assembled upon the free extremity of the base section 6 completing a three-quarter circle of the ring core. The terminal segment 7 is' then merely put into place upon the free extremity of the base section 5 and is swung until the segments 7 and 8 mate along their slant lines 9 and 23, the entire group of 'sections thus assuming the ring form shown in the full lines of Fig. l. A locking ring 24, bears a central annular groove which provides an annular lug 25 to be aconimodated within the complete groove 16, as the latter is formed by the successive mating of the separate segments, as illustrated in Figs. 1 and The opposite annular lug 26 formed by this grooved ring 24 engages the interior diameter of the complete core and functions in cooperation with the ring lug in groove 16 to prevent any disassemblage of the core segments from their ring foi-m, since such disassemblage must be first accompaniedby a partial swinging of the successive segments upon the adjacent core sections mounting them. This requisite swinging of the segments for disassembling them is prevented when the locking ring 24 is in place.

To remove the core of this invention from the interior of a tire casing, it is necessary only to first displace the grooved annulus 24, to next swing the terminal section 7 inwardly, and then unhinge both of the end sections 7 and 8 from the remaining pair of sections, which may be immediately disconnected and removed from the tire interior.

What I claim is:

1. A core for forming tires and carcasses oftires, including a plurality of segmental sections provided Qwith web portions anf ist from adjacent sections and removed one at a time by merely edecting relative movement between them and the adjacent `sections?, such connections comprising a tongue formed on the web portion of one section to extend into an :mpropriateI recess in lxthe web portion of the other section, and hinge means associated with said tongue and recess.

2. A core for forming tires and carcasses of tires, including a pluraiity oil segmental sections having web portions and adapted to 'be formed into a complete core annulus, said web portions provided with grooves therein; connectionsprovided for the removable pivotal securement of certain of the sections to adjacent sections, such connections compris ing a tongue formed on the web portion ot one section to extend into an appropriate recess in the web portion of the other section, and 'hinge means associated with said tongue and recess; and a removably secured assemv bly ring provided with a lug fitted in said grooves to group' all of the sections in their assembled relations and to maintain them therein.

3. A core for forming tires and carcasses 'of tires, including a plurality ofv separable core members having web portions and adapted, to be assembled to provide a comf. plete core annulus; `a pair of adjacent inem-V bers being mated along a slant line'and the remaining members being mated along lines radial with respect to the core annulus, and

. means including tongues and recesses on the web portion providing hinge connections for p removably securing the radially mated core members to each other.

d. A core Jfor forming tires and carcasses of tires, includinga plurality of separable core members having web portions and adapted to be assembled to provide a comn plete core annulus, said web portions provided With grooves therein; a pair of adjecent members being mated alon a slant line and the remaining members being mated along lines radial with respect to the core annulus; means including tongues and recesses on the web portions providing hinge connections for removably securing the radially mated core members to each other; and an assembly ring having a lug arranged in the groove of all the members to collect and maintain them in a unitary group.

5. A forming core for tires and carcasses of tires, including separable sections having adjacent extremities ofthe inner portions thereof beveled, one of the sections being provided with a recess in the end extremity of its inner portion, and With a hinge pin in said recess; and the other section being provided with a tongue in the end extremity of its inner portion, said tongue being adapted to lit in said recess when the sections are assembled, and said tongue being provided with a recess to receive said pin yto form a hinge connection between the sections.

6. A forming core :tor tires and carcasses of tires, including separable sections, one ot the sections being provided with a recess in the end extremity of its inner portion, and
